What is the minimum clear width required for stairways in residential construction?

In residential construction, the minimum clear width required for stairways is 36 inches. This dimension is important as it ensures that stairways are accessible and safe for use by occupants, enabling the comfortable passage of individuals, including those who may be carrying objects or assisting others. A clear width of 36 inches meets the requirements outlined in the North Carolina Building Code, providing adequate space for safety and maneuverability.

Choosing a width less than this, such as 30 inches, would not provide sufficient space for safe navigation on the stairs, particularly in emergency situations or when accommodating larger items or individuals. Wider options like 42 inches and 48 inches, while safe, are not the minimum requirement and may not be necessary depending on the specific design considerations of the residential project. However, ensuring compliance with the 36 inch minimum is critical for meeting building and safety codes.
